From the author of Gorky Park comes a novel of earth-shattering proportions. Four men cross a barbed-wire fence at Stallion Gate to select the test site for the first atomic weapon. They are Oppenheimer, the physicist, Groves, the general, Fuchs, the spy, and Sergeant Joe Pena. Four men in a covert world of soldiers and scientists, roughnecks and rougher women, all about to partake in the most important ten seconds the world has ever seen.
